If your grandparents were using the driveway and well a new buyer might have a case to take that portion of your dads property via adverse possession.

I know here in CA, if your screening criteria is 3x rent, you can only require a S8 tenant to make 3x their portion of the rent as income. 

That hurts your returns.With a pool, or a big enough pot of your own cash, like your friend, the lumpiness is reduced because a large portion of the cash is invested most of the time.  

If I have to hire a pro, there is no portion stating that I need to keep receipts and prove it really, I just have to have the inspector come back to the house and verify that it is up to code.I guess I am just confused now as to what constitutes a do-it-myself kind of job versus what I have to hire someone to do.  

If he decides to obtain a Realtor, who's portion will that expense come from...

One of the podcasts I listen to mentioned the possibility of large corporate investor selling off portions of their portfolios, potentially at their loss and our/the investor's gain.Has anyone read/heard the same thing?

I'm just wondering if there is a general rule of thumb as it relates to what portion of your rental income should offset the property taxes?  

Im considering the strategy borrowing from my 401K and using investors. not sure how to structure the investor portion of it.

Thank you @James Tran  , I was was leaning towards multi family property because of the fact that I can leave for free, or at least have the tenants pay a large portion of the mortgage.The only issue is that at my price range, I'll have to find myself living at the "not so good" areas of SFV or LA.Any recommendations for locations ?  

A lease purchase is a lease with another agreement so they can interfere with the lease portion and possession by a tenant.
